Title: Exploring Doubles and Near Doubles in Single Digit Addition

Objective: By the end of this 30-minute lesson, Year 3 students will be able to understand and apply the concepts of doubles and near doubles in single-digit addition. They will be able to identify doubles and near doubles, and use this knowledge to solve addition problems.

Materials: - Whiteboard or chart paper - Markers or colored pens - Manipulatives (e.g., counters, cubes, or small objects) - Printed worksheets or activity sheets - Computers or tablets with internet access

Lesson Plan:

1. Introduction (5 minutes):
   • Begin the lesson by engaging the students in a discussion about addition and how it can be made easier.
   • Ask the students if they have heard of doubles and near doubles in addition.
   • Explain that doubles are when you add the same number to itself, and near doubles are when you add two numbers that are very close to each other.
   • Share the learning objectives for the lesson.
2. Doubles and Near Doubles Explanation (5 minutes):
   • Write the following examples on the whiteboard or chart paper: 1+1, 2+2, 3+3, 4+4, 5+5.
   • Ask the students to identify what they notice about these addition problems.
   • Guide the discussion towards the concept of doubles and explain that when we add the same number to itself, it is called a double.
   • Write the following examples on the board: 1+2, 2+3, 3+4, 4+5, 5+6.
   • Ask the students to identify what they notice about these addition problems.
   • Explain that these are near doubles because the numbers being added are very close to each other.
3. Hands-on Activity: Doubles and Near Doubles (10 minutes):
   • Distribute manipulatives to each student.
   • Instruct the students to work in pairs or small groups.
   • Provide a set of addition problems involving doubles and near doubles on the printed worksheets or activity sheets.
   • Ask the students to use the manipulatives to solve the problems by physically representing the numbers being added.
   • Encourage the students to discuss their thinking and strategies with their partners.
4. Online Resource Exploration (5 minutes):
   • Introduce the students to online resources that reinforce the concept of doubles and near doubles in single-digit addition.
   • Share the links to interactive games or websites that provide practice and reinforcement.
   • Allow the students to explore the resources individually or in pairs on computers or tablets.
5. Conclusion and Reflection (5 minutes):
   • Gather the students back together as a whole group.
   • Ask the students to share their experiences and discoveries during the hands-on activity and online exploration.
   • Recap the main concepts of doubles and near doubles in single-digit addition.
   • Provide opportunities for students to ask questions or seek clarification.
   • Assign additional practice worksheets or activities for homework, if desired.

Note: It is important to adapt the lesson plan to suit the specific needs and abilities of your students.
